58km longdistance high bandwidth digital wireless equipmentDescription:

SF-5040G high power outdoor wireless bridge is very suitable for the wireless internet connection under the wild environment,it satisfies the needs of high bandwidth network connection and the transmission of multimedia IP data.It's suitable for not only network transmission but also large IP monitoring.SF-5040G high-power outdoor wireless bridge equipment can use the built-in 18dBi gain antenna to link two long-distance nodes effectively, transmission distance can reach 8km, transmission bandwidth can reach 80-90Mbps, can provide no less than the quality of wired network.

SF-5040G high-power outdoor wireless bridging equipment supports AP mode, WDS mode, ClientBridge + Repeater AP mode, the cooperation between different modes can achieve different effects, you can do point-to-point transmission, point to multipoint transmission. In WDS mode, you can achieve 1 to 8 (fill in 8 different MAC address) link form, in AP mode, can support 32 clients in theory.The device supports Chinese and English interface, simple operation, remove the cumbersome mode of operation, so you can debug more quickly and easily, is conducive for rapid deployment, very suitable for engineering and technical personnel to get started quickly.Power supplies DC12 ~ 24V wide voltage input design, and the actual power consumption of the device is less than 5W, in the absence of electricity in the case of the city can be flexible with batteries, solar energy, wind and other power supply work.

Key features:

L Operation mode: support AP mode, WDS mode, ClientBridge + Repeater AP mode
